To 00% whom it may concern.-

Be it known that we, GEORGE S. EATON and JAMES C. BIRCH, of Brooklyn, .in the county ofKingsand State of New York, have invented an Improvement in Machinery for Rubbing Types, of which the following is a specification.

In this machine we have improved upon the type-rubbing devices shown in Letters Patent No. 278,785, granted to George S. Eaton. \Ve make use of cheek-pieces between which the types are supported and smoothed as they are moved along one at a time, and while being moved the burrs or projections at the bases of the letters are removed by stationary cutters; but the cheek-pieces are straight and the bod yplunger reciprocates in a straight line. The type, after two of its sides have been dressed, is carried off at right angles to its first movement and passed between stationary cheekpieces and cutters to finish the other two sides of the type, and it is set up in line in a stick or rule. The bases of the types are nicked, and the dust and fine metallic particles are discharged and blown from the machine, so as not to adhere to or injure the types.

In the drawings, Figure l is a plan of the driving-shaft and parts connected therewith, the bed and rubbing mechanism being removed. Fig. 2 is a view of one end of the machine. Fig. 3 is a face view of theinclined bed and type-rubbing mechanism perpendicularly to the surface of such bed. Fig. 4 is a section of the running-way slideat the line a; m, Fig. 3. Fig. 5 is a section of the bodyplunger slide at the line 3 y, Fig. 3. Fig. 6 is a side view of the running-way and slide. Fig. 7 is a similar view of the body-plunger and slide. Fig. 8 is an end view showing the cutter for fretting or nickiug the bases of the types. Fig. 8 is a side view of the same. Fig. 9 is a section of the forward end or" the body-plunger. Fig. 10 is a view, in smaller size, of the surface of the bed, the check'pieces, cutters, and other parts being removed. Fig. 11 is a face view of one form of the feeding Fig. 12 is a section of the bed and elevation of the concave type-guide at the delivery portion of the machine. Fig. 18 is a face view, and Fig. 1% an versiug device. Fig. 17 is a section of the bed-cutters and cheek-pieces; and Fig. 18 is a view, in larger size, of one of the cutters.

The types, as they come from the castingmachine, are laid upon the table A in mass.

This table A is supported by columns A, ris- 6o ing above the base plate or frame A The table A is preferably fiat and level, and it is provided with a fence or bar, a, screwed to its upper surface, and at a there is a zigzag or offset forming an angle in the fence. The 6 length of this offset is less than the usual length of the sprue or gate that remains upon the bases of the types after they are cast, and there is a hole at a passing through the table A, so that the operator grasps the types insuccession,

moving each onearound until the gateispressed against the offset in the fence with sufficient force to break the gate off the type. This gate falls through the hole a", and is received as waste metal into a box or receptacle placed be- 7 5 low the opening. The operator passes the type, base first, down the groove a? to the feeding mechanism, hereinafter described.

Upon the bed 0 the rubbing and dressing devices are secured. This bed is preferably at an angle of about forty-five degrees to the horizon in one direction; but the upper and lower edges are level, or nearly so.

Between the table A. and the bed 0 an inclined chute, D, is placed with the feed-regulating devices, hereinafter described.

Upon the bed 0 there are the cheek-pieces E E The piece E is stationary, but. the pieces E E are adjustable. They are clamped to the bed by the screws 6 e, and these pass through elongated holes, so that the cheek E can be moved by the screws e toward or from the side of the stationary cheek E. The end of the cheek E is in line with the end of the cheek E, and the cheek E is opposite the ends 9 5 of E and E and it is adjustable by the screws 6 The checks are of a thickness to allow the letter ends of the types to be above their top surfaces, and these checks are adjusted so that the distance between E and E corresponds to I00 the breadth of the body of the type to be acted upon, and the distance between E and E corresponds to the thickness of the type-body and the width of the line of types.

Each type is passed down, base first, between the cheeks E and E, and by the body-plunger g the typeis carried along between the cheeks E and E and brought up to the side of the cheek E, at which moment the running-way h comes up against one of its sides and carries the said type along at right angles to its first movement and between the cheek E and the end of the cheek E.

The devices for moving the plungers g and running-way h are hereinafter described, and we remark that the cheek-pieces are made with hard and smooth surfaces that are parallel to each other, and they straighten the type-body and hold the type in its proper position in relation to the cutters which dress off the burrs at the base of the letter. The cast types are sufficiently accurate in their thickness not to require any metal to be removed from the body portions. The cheek-pieces only smooth and straighten the body portions by contact therewith as the types are pushed along between them.

The cutters are shown at H H. They are I upon the top sides of the cheek-pieces E E E and they are each made with a row of cuttingteeth having flat ends, and they are held in place by the screws 5 and adjusted up accurately to place by the screws 6, so that the ends of the last teeth correspond to the surfaces of the cheeks, and they are placed so as to cut away the burrs gradually, the last cutting-edges acting to bring the surfaces of the burrs or letter-bases into line with the surfaces of the type-body. The cutters Z Z act in the same manner as the cutters i, but they dress off any burrs or projections at the top and bottom edges of the letter.

The bed 0 has a groove or slot in line between the cheek-pieces E E, of a width sufficient to allow the rough part of the base of the type to pass into such slot; but the shoulders or smooth parts of the letter-base rest upon the surface of the bed, and the rough portion of the base where the gate was broken off is removed, and the type channeled by the cutter or fretting-tool 10, that is attached to the under side of the bed, and the cutting-edges project slightly above such bed, as seen in Figs. 7 and 8.

The slots in the bed are shown in Fig. 10, and we remark that it is preferable to employ a pipe, 65, leading from a suitable blower, and nozzles placed over the raceway for the types, by which pulsating currents of air will be directed upon the type, the cheeks, plungers, and cutters to remove any dust or metallic chips and prevent the said particles injuring the machine or adhering to the plungers as they press the type along between the cheekpieces.

The body-plunger g is grooved longitudinally upon its upper and lower edges, as seen in Fig. .9. The groove at the top forms achannel along which dust and particles of metal will pass away, and the groove at the under edge allows the body-plunger to pass along.

over the cutter 10 without touching the same. This plunger 9 is attached to the stock 9 beneath the bed, and such stock has a dovetailed body within the stationary slide g, that is formed with or attached to the bed 0. The stud projects from the stock through a slot in g and receives the link connected to the lever and this lever g is pivoted at g and receives its motion at the proper time and of the desired extent from the cam K upon the driving-shaft L.

The stud or roller upon the lever g enters the groove of the cam K, and the shank of the stud that passes into such lever g is adjustable toward or from the fulcrum of the lever in order that the amount of motion given to the body-plunger 9 may be varied to suit the thickness of the types and for compensating for wear. This adjustment may be effected in any desired manner. We have shown by dotted lines, Fig. 2, the shank of the stud within an elongated hole and screws at opposite sides to clamp and adjust the stud.

The pusher h is similarly mounted, its stock h sliding in the bar If at the under side of the bed 0 and receiving the proper motion from the cam H, upon the driving-shaft L, acting upon the lever h, that is pivoted at h and provided with a link, h, connected to the stock h.

The pivot h is upon a block,h ,that is clamped upon the rod h, which block can be moved along upon such rod for adjusting the pusher h, in order that its end may be in its proper position to act upon the types as presented to it. justment.

Upon reference to Figs. 2 and 7 it will be.

seen that the bed 0 is at an inclination and that the slide D, down which the types are fed, one at a time, is also at an inclination; but it is at right angles to the bed 0, so that the types, as they pass down the feedingchannel, slide across the end of the body-plunger g. It is necessary to allow the type to pass down after the body-plunger has been drawn backwardly and downwardly. To do this,the type is held, until the proper moment arrives by any suitable detainer. We have showntwo forms of this detainer, one in Fig. 11 and the other in Figs. 13, 14, and 15.

There are fences q q upon the plate I), and these are adjustable by screws passing through slots, so that these can be Varied according to the height of theletter. The plate D is notched, and the body-plunger 9 moves back and forth in the notch. There is a friction-finger, r, that passes in through a mortise in the fence g, and this is supported so that it can slide freely back and forth.

The stock 0 upon the bed 0 holds the rockshaft 1, at one end of which is an arm, r resting upon the body-plunger 9 near the rear end. (See Figs. 2 and 11.) At the other end Wear is also compensated for by this adof the rock-shaft 1' there is a crank, r the pin of which passes through a hole in the plate D and acts against the friction-finger r to move it toward the stationary fence q, and the spring 20 tends to move the finger in the same direction. Upon the top edge of the body-plunger there is a depression at r, Figs. 2 and 7.

When the body-plunger 9 reaches its extreme forward and upward movement, the cam portion 1- raises the arm r and swings the rock-shaft and draws back the finger 1' and allows the types to slide down the feeding slide, the bottom of the lowest type resting upon such body-plunger 51. As soon as the body-pusher commences to draw backwardly and downwardly, the cam 2' draws from under 9' and the spring 20 presses the finger r upon the second type in the feeding-slide holding the same, and when the body pusher has drawn entirely back the lowest type slips down in front of its end to be carried by such pusher in between the cheek-pieces E and E and be dressed, as aforesaid, and the operations are repeated. We, however, prefer to provide a double-acting detaining finger. (Shown in Figs. 13, 1-.t, and 15.) In these figures the finger r is pivoted at s and provided with a tail, 3', coming around to the feedingslide a so that when the frictionfinger 7' is drawn back, as before described, by the rockshaft r and arm 1' the tail-piece s is moved into the feedingslide and catches the lower end of the type as it falls after being liberated by the backward movement of the finger r, and thereby the tail 8' holds up or supports the type, and its lower edge does not rest upon the top edge of the body-plunger g. In this form the portion s, Figs. 2 and 7, of the plunger 9 acts as a cam on the backward movement of said plunger to cause the finger r to drop a type and the tail 8 to pass below and catch it, and then the tail moves back as the finger 1' is again made to hold the second type in the feeding-slide, and the tail 3 drops the type in front of the plunger just as it comes up to it.

The spring a bears frictionally on the side of the finger r to steady the same in its move ments, and the gate t, pivoted at t, hangs with its flange t in proximity to the typeasitslides down beneath such flange to prevent the type jumping out of its place in the feed-slide. The screw t, through t, adjusts its position, so that the edge of the flange it will not ob street the type in its movement.

In delivering the type from the machine the plunger It carries such type to the extreme corner of the cheek-piece E, where it descends into the curved raceway a between the quartercircle block a and similar fence, at, and it is carried away upon a rule or galley, a which is horizontal; but in consequence of the table 0 being at an angle the types lie in the angle of the rule a. (See Fig. 16.) The under surface of this quarter-circle fence a is not in con tact with the bed 0, but is supported by the cheek-piece B, so that there is a cut-away portion, a, through which metallic particles or chips can escape, and the bed 0 is channeled at a at the bottom of the curved raceway a, as seen in Figs. 10 and 12, such channel having an inclined bottom that rises up to the surface of the bed 0, the object of this channel being to prevent any friction on the base of the type by its touching the bed as the types are discharged from between E and and pass down into the curved raceway u and around through the curved raceway to the rule or galley.

There is a cam, 12, upon the shaft L, which acts upon the lever v, )ivoted at c and at the upper end of the lever is the pushingblade o that passes through a slot in the bed 0 and extends above such bed, and this pusher is at the end of the cheekpiece E and it is so timed and acted uponby the cam c that it comes against and presses upon the type immediately after being delivered from between E and E, and the type is carried down until its upper surface is'in line with the end of the cheek-piece E, so that the next type will pass freely out over such type.

The lower edge of t-heconcave type-guide a, next to the bed 0, is cut away, as seen at a in Fig. 12, so that any dust upon the types may be blown down and pass away through such opening instead of being carried along with the types.

The rule a is connected to the side of the bed Cby a bolt, 10, and there is a stop, 25, upon which the flange of the rule rests to hold it in position for receiving the types. The rule preferably has a rectangular recess to receive the movable stick 21,0f wood or metal, so that this can be taken out when full of types and another substituted. The bolt in also forms a pivot, so that a metal rule, 23, (shown by dotted lines in Fig. 16,) may be laid upon the line of types and the rules given a half-revolution to invert them and cause the rule 23 to bebelow the rule a, and hence receive the type, and in which they are conveyed away from the machine, after which the rule a is turned back to its normal position.

In order to prevent undue pressure or concussion upon the type by the body-plunger 9, when one side of such type comes up against the side of the fence Ff we make useof ascrew which limits the movement in this direction of the stock g of said body-pusher g.

It is convenient to provide a block, 30, at one side of the stock 9, and to place a lever, 31, beneath the bed 0. The block 30 stops against this lever, and the screw 32 is used to adjust this lever for the purposes aforesaid.

Ne claim as our invention 1. The combination of the bed 0, the stationary cheek piece E, the movable cheekpieces E E all having smooth flat surfaces between which the types are moved, and means for adjusting and holding the movable cheek-pieces, the cutters fastened upon the top surfaces of the cheek pieces, the pushers acting at right angles to each other, and the mechanism for actuating the same, substantially as set forth.

2. The combination, with the inclined bed, the cheek-pieces,the cutters, and the pushers, of a feeding-slide at right angles to the inclined bed for feeding the types into the channel between the cheek pieces, substantially as set forth.

3. The combination, in a type-rubbing machine, of an inclined bed, cheek-pieces, cutters and pushers, a feeding-slide at right angles to the bed, and a spring detaining-finger, and means for drawing back such finger and allowing the types to feed, substantially as set forth.

4. The combination, in a typerubbing machine, of an inclined feeding-slide and a horizontal table to receive the type,and having an opening in it and a fence with an angle adjacent to the opening and against which the gate or sprue is broken off as the typeis moved by hand on the table, substantially as set forth.
